Lösung

∣ 5 x + 2 ∣ = 12

x = - \frac{14}{5} or x = 2

Dezimale

x = - 2.8, x = 2

Schritte zur Lösung

∣ 5 x + 2 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x + 2 = - 12 or 5 x + 2 = 12

5 x + 2 = - 12 or 5 x + 2 = 12

x = - \frac{14}{5} or x = 2

- ∣ 1 - 5 x ∣ + 3 = - 6

∣ 5 v - 4 ∣ = 7

∣ x + 3 ∣ = 2 x + 1

- 2 = - 4 ∣ y + 2 ∣

\frac{x}{a} = b
